Attaching Vac Sensor housing support bracket <br /> Attaching Vac Sensor Cables and Tagging Vac SensorNac Float Pairs <br /> 1. Next get the Vac Sensor cables (with connectors on one end)from the kit(s) and attach the connector of each <br /> cable to each of the Vac Sensor ports labeled TLS (on the Vac Sensor cover). Uncoil each of the Vac Float <br /> cables. Notice that each Vac Sensor,except the one for the tank interstice, has a short piece of tubing <br /> connecting it to a Vac Float beneath it (diagram A in Figure 7). In installation diagram B of Figure 7,there is no <br /> tank interstitial sensor,but there is a Vac Sensor monitoring the tank vent line interstice.A Vac SensorNac <br /> Float tubing connected pair must be wired together in the junction box. <br /> 2. Use a felt pen and write on the top of the Vac Sensor housing to what device each of the Vac Sensors below <br /> will be attached (see Figure 8). For example,P=product line,S=sump interstice,V=vapor line, and T= <br /> tank interstice,or TV=tank vent interstice. NOTE:There is no particular order except that the Vac Sensor that <br /> is not attached to a Vac Float must be assigned to the Tank interstitial space (diagram A),so make a'T' mark <br /> over that Vac Sensor. If the made you wrote on the housing over the first Vac Sensor was'P',locate the cable <br /> ends of this Vac SensorNac Float pair,tape them together about every foot along their length and at their <br /> ends,and tag the end of this cable pair'P'or'Product Line Vac Sensor. Repeat this taping and tagging for <br /> each of the Vac SensorNac Float pairs.The Vac Sensor marked'T'will only have one cable,so tag the end of <br /> this cable'T'for'Tank Vac Sensor'. <br /> 7 <br />
